DESCRIPTION
Multiplying powers with the same base. Add the powers of like bases. ( x m ) ( x n ) = x m + n. 5 3 • 5 3 = ( 5 • 5 • 5 )( 5 • 5 • 5 ) = 5 3+3 = 5 6. x -2 • x 4 • x 6 = x -2+4+6 = x 8. Raising an e xponent to a power. Multiply the powers of each base. ( x m ) n = x mn. - PowerPoint PPT Presentation

(xm) (xn) = xm + n
Multiplying powers with the same baseAdd the powers of like bases
53 • 53 = (5•5•5)(5•5•5) = 53+3 = 56
x-2 • x4 • x6= x-2+4+6 = x8
(xm)n = xmn
Raising an exponent to a powerMultiply the powers of each base
(53)4 = 53•53•53•53 = 53•4 = 512
(5x3)4 = 5x3•5x3•5x3•5x3 = 51•4x3•4 = 54x12
